We will likely do Example 1 (Item G) -- The ANSWERS

G     Example #1  --  A differentially permeable membrane pouch containing distilled water was
        placed in a beaker of 5% sugar solution. 

         1     Draw & label all stated information (distilled water, 5% sugar) on a diagram

 

 

                                                       100% water
                                                                                  
                                                     5% sugar
                                              G       95% water

Distilled water                                    

            Beaker                              Pouch

        I have a problem in that Word does not allow me to place text (100% water) within the oval
        where is belongs.  Please label your diagram where the labels belong.

         2     Change the solute (sugar) concentration into water conc. (5% sugar = 95% water)

         3     Draw a thick arrow showing water diffusion (from 100 to 95% water is out of the pouch)

         4     Place a “G” where water & mass is first gained.  (outside the pouch gains water/mass)

                                    (Now its your turn!)

H      Example #2 --  A selectively permeable membrane pouch containing a 2% salt solution was
        placed in a beaker of 1% tea.

         1     Draw & label all stated information on a diagram

         2     Change the solute concentration into water conc.

         3     Draw a thick arrow showing water diffusion

         4     Place a “G” where water is first gained
